Description

Technical Field

[0001] The utility model relates to the technical field of cutting machinery, in particular to a burr cutting device for processing injection molding barrels. Background Art

[0002] Plastic barrels are a type of plastic product used to store various liquids and are widely used in industrial production and daily life. They are often made of materials such as polyethylene or polypropylene through injection molding. After injection molding, there are often some burrs on the surface of the barrel, so the burrs need to be cut and removed by a cutting device.

[0003] For example, in the patent document with patent publication number CN215242305U, a burr cutting device for injection molding barrel processing is disclosed, which includes a workbench, four support rods are fixedly installed on the lower surface of the workbench, a groove is provided in the middle of the upper surface of the workbench, a rotating mechanism is provided in the groove, a grinding and cutting mechanism is provided in the middle of the upper end of the upper surface of the workbench, the rotating mechanism includes a No. 1 motor, the No. 1 motor is installed at the bottom end of the groove, the output end of the No. 1 motor is fixedly connected to the lower end of the No. 1 rotating rod, the upper end of the No. 1 rotating rod is fixedly connected to the middle of the lower surface of the rotating plate, and fixing mechanisms are fixedly installed at both ends of the upper surface of the rotating plate, the fixing mechanism includes a No. 1 fixing block, and the grinding and cutting mechanism includes a fixing frame.

[0004] According to the existing technical literature, the cutting device can clamp and fix the circumferential outer wall of the injection molding barrel through a semicircular fixing plate, and then remove the burrs on the injection molding barrel through the cutting and grinding machine when the No. 1 motor drives the injection molding barrel to rotate and the No. 2 motor drives the cutting and grinding machine to rotate. However, in order to adapt to injection molding barrels of different sizes, it is necessary to manually adjust the position of the semicircular fixing plate and the cutting and grinding machine, so as to clamp and fix the injection molding barrel and perform cutting and grinding on it, which has low work efficiency; at the same time, the position of the semicircular fixing plate and the cutting and grinding machine is limited by inserting the pin into the corresponding socket, so the position of the two is determined according to the position of the socket, so the flexibility of position adjustment becomes poor, and only a few injection molding barrels of specific sizes can be cut and polished, which has poor adaptability; in addition, the cutting and grinding machine cannot effectively grind and cut both the inside and outside of the injection molding barrel at the same time, which further reduces the work efficiency.

[0005] To this end, the utility model optimizes and improves the problems of low cleaning efficiency and poor adaptability to injection molding barrels of different sizes in the prior art. Hereby, a new cutting device is proposed which can flexibly adapt to injection molding barrels of different sizes and can simultaneously remove burrs from the inner and outer barrel walls, so as to better solve the problems in the prior art.

[0026] The motor 1 is fixedly installed on the ground at the corresponding workstation through the motor frame, and its motor shaft is vertically arranged and coaxially fixedly connected with the first rotating shaft 2 through the coupling. The operation of the motor 1 drives the first rotating shaft 2 to rotate, and then drives the first fixed disk 3 to rotate. The upper end of the second rotating shaft 5 is integrally formed with an annular protrusion, and a step-shaped rotating groove matching it is provided at the bottom of the fixed block 6. At the same time, the fixed block 6 is composed of two semicircular structures, so that the annular protrusion at the upper end of the second rotating shaft 5 can be flexibly clamped in the step-shaped rotating groove, thereby realizing the active connection between the second rotating shaft 5 and the fixed block 6, and then the second fixed disk 4 can rotate freely.

According to the diameter of the injection barrel 9, the third hydraulic cylinder 20 is controlled to extend and retract, so that the two tools 16 are moved to the appropriate position with the cooperation of the slider 22 and the slide rail 23, and then the second hydraulic cylinders 10 are controlled to retract, thereby driving the tools 16 to move downward until the two tools 16 are finally moved to the inner and outer sides of the left barrel wall of the injection barrel 9 respectively, and then under the joint action of each horizontal electric cylinder 14, the corresponding tools 16 are driven to move, so that the blade of the tool 16 abuts against the circumferential barrel wall on the corresponding side of the injection barrel 9, and at the same time, the tool 16 is heated by the electric heating wire 19 to quickly increase its temperature.

[0042] Then start the motor 1 to make the injection molding barrel 9 rotate around its own axis.
